Standard Fallout Shelter Signs
The two most common fallout shelter signs are shown above. The FS1 which is a 14 by 20 inch aluminum sign and the FS2 which is a 10 by 14 inch galvanized steel sign. Both have flat black and yellow reflective paint. The Fallout Shelter Sign Posting Handbook lists the FS 1 as an exterior sign and the FS 2 as an interior sign but both were posted on the exteriors of buildings with shelters. All DOD OCD issue signs have "Not To Be Reproduced Or Used Without Department Of Defense Permission." at the bottom of the sign. The paper adhesive backed sign (see below) also has the DOD FS No. 2 number designation at the bottom of the sign.

Mr. Blazich also sent me an image from a DOD OCD Region 3 Newsletter. It's Volume 1 No. 2 March 1963. On this page there is a paragraph written as follows...
Before seeing this I had no idea that the shelter sign "points" had ever been assigned any meaning. I have never seen the statement by Mr. Pittman mentioned in the paragraph in any other document that I have but since this is a DOD OCD Regional Newsletter I think it's probably a good source to cite. I guess it's something they never really followed up on as a promotional effort.The original document of the Region 3 Newsletter image file. DODOCDReg3NewsletterVol1No2.jpg
Thanks again to Mr. Blazich for this image!

Adhesive Backed Paper Fallout Shelter Signs
There were also 9 versions of the 7 by 9.75 inch adhesive backed paper signs. The paper signs were also flat black and reflective yellow. The above left image is a scan from the DOD OCD Posting Fallout Shelter Signs booklet supplement FG-C-8.1A dated January 1970. The supplement says these signs can be used in lieu of the Type II interior metal shelter signs under certain conditions. The supplement also says the adhesive signs are intended primarily for interior marking, although in the event of a declared emergeny, they can be used for both interior and exterior marking of all available shelters. The adhesive backed paper signs are not mentioned in the FG-C-8.1 booklet dated June 1964. I belive the paper signs were issued a bit later than the original metal signs. I have a package of paper signs and the instruction cardboard backing of the package has a 7/67 date on it.
Fallout Shelter signs came with adhesive overlays to mark capacity or more clearly point out the shelter locations. These are described in Section D of the Posting Fallout Shelter Signs Handbook linked above. Shown below are some examples of overlays from leftover pieces of overlay sets I have that came with shelter signs I have. I do have some complete sheets of overlays but they are packed up inside a case of shelter signs that I have in my collection. The "capacity" circles were for adding capacity markings to the smaller FS 2 sign above. There were also Spanish and Samoan overlays as pointed out in the Fallout Shelter Sign Posting Handbook (see link to Handbook scans above.)
These small decals were also used. They measure about 1-5/8 by 2-3/4 inches and are water transfer decals. I presume they were ususally put on windows or doors at the front entrances of buildings. I have never seen any still in place in person though.
The fallout shelter triangle symbol is often confused with the international radiation symbol for obvious reasons (see image below). The radiation symbol goes back to just after World War II. For a history of the radiation symbol (Trefoil) see Oak Ridge Associated Universities Health Physics Museum Page here. When I look at the radiation trefoil I see 3 "fan blades" radiating from the center, however, the fallout shelter triangle emblem has always looked to me like 3 triangular "arrows" pointing down instead of fan blades radiating out from the center.
Bill Geerhart put together an excellent article about the History of the Fallout Shelter Sign (I wish I had the time and could afford to research stuff like this) where he cites the "very first sign unveiling ceremony at the Westchester County Building in White Plains, New York at 148 Martine Avenue on October 4, 1961. Check out his article f you have time. He even interviewed the man was in charge of developing the sign.
Here are a couple of shelter signs in downtown Dallas. The old Dallas Public Library is a classic mid-century modern work with a shelter sign next to the loading dock door at the rear of the building. The George Allen Courts Building has the highest capacity of any shelter sign I have ever seen. The capacity on the sign is 28,850! Click on any photo to see a larger version.
Company Made Fallout Shelter Signs From Textile Mills
This image and caption are from CD publication number FG-F-3.30 January 1970 "Civil Defense in the Textile, Apparel and Related Industries." This book has info and various photos from several textile mills in Alabama. According to the book the Langdale and Shawmut mills operated by West Point-Pepperell had this type of shelter sign designating different areas in the mills as fallout shelters. The book shows how the West Point company had an extensive company civil defense program. I have never seen this type of sign anywhere else so I believe the company must have had them made.
I got the sign in the above photo from an ebay seller in May of 2011 who informed me that it came from the Fairfax textile mill in Alabama. Obviously it's the exact same type of sign pictured in the FG-F-3.30 publication mentioned above. The sign measures 12 by 16 inches. The seller stated the following when I inquired about where the sign came from. "My husband wanted me to tell you that it's not the Langdale or Riverview or Lanett Mills. It's the Fairfax Mill and it's actually being torn down." The Fairfax mill isn't mentioned in the FG-F-3.30 book but I believe it was operated by the West Point company like the other mills mentioned in the book. The mills were loacated in what is now Valley Alabama.Company Made Sign From Steel Mill
Brian Abbott of Parkersburg, West Virginia sent me photos of this sign in 2014. He said it measures 14 by 24 inches and is procelain on heavy steel sheet. It is from a steel mill but he did know which mill it came from. Thank You Brian for taking the time to send the photos of this unique sign.
I got these paper signs from an ebay seller around 2004 or so. They are adhesive backed, are flat yellow and black but the yellow is non-reflective. The larger sign measures 9-1/2 by 8-3/8 inches. The smaller sign measures 9-1/2 by 4-1/2 inches. If I remember correctly the seller told me they were from an air force base, for what that's worth.
